Join author Brian Trifon as he shows how to improve music and audio productions using virtual instruments in Logic Pro. This course tours the program's virtual instruments, including the ES2 hybrid synthesizer, Sculpture physical modeling synthesizer, EFM1 FM synthesizer, the EVOC 20 vocoder, the Ultrabeat drum synthesizer, and the EXS24 sampler, and shows how to achieve various effects with each instrument's parameters. The course also covers working with oscillators and filters, understanding signal flow, creating custom synthesizer patches, adding effects, synthesizing speech, creating a library of custom sound samples, and much more.
Virtual Instruments with Logic Pro will be updating on a monthly basis, eventually covering all the virtual instruments in the application. Look for the latest movies here and on the lynda.com blog.
So let's take a look at the Vibrato section down in this Modulation area. So I will click on Vibrato. Notice this looks a lot like the LFOs that we saw, so LFO 1 and 2. So if we go back to Vibrato, you can see we have got the Waveform selection, Curve, Phase, Rate, Sync, and Free. That's because this is an LFO. Vibrato is an LFO that's dedicated to modulating pitch. So if you want to refresh your memory on how the LFO features work, make sure to watch the video on LFOs.
So let's take a look at the new parameters that introduce Vibrato. So we have the Amount for Vibrato right here. So I can adjust the amount of Vibrato for the sound, so I will play a note-- (music playing) --and as I increase the Amount, we get more pitch modulation. And I can also use a MIDI Controller to control the depth of the vibrato. So, that's this parameter right here, but first I have to actually assign the MIDI controller. So, if you look down at the bottom, we have got MIDI Controller Assign, and so the first selection that we have here is Vibrato Depth Control.
So I am going to select what I want to control that. So I am going to choose Mod Wheel. Then what I have to do is set the range that I want the mod wheel to control the depth. So I will set it so that it controls quite a bit of range. If we have the Mod Wheel all the way closed, we'll have no vibrato. If we open it up, we will have a really wide pitch modulation. So I will play the note and I have the Mod Wheel closed. So, no pitch modulation, and I will open it up, and you can hear there is a lot of vibrato. (music playing) So I will go ahead and set this back to its default setting by Option+Clicking, and what I am going to do is get rid of this Vibrato Depth Control here.
So I am going to select this menu and set it to off. On the next tab, we have Velocity controls and Note On Random controls. So let's take a look at the Velocity controls first. So we can have velocity modulate any parameter in the sound engine. So I will turn on Target 1, and then in the Target list I will choose what I want to modulate with the velocity. So for this first one, I will choose PickupA Position, and so now what I can do is move the Amount slider right here, and we will give that a positive amount.
What it's going to do is depending on how hard I am playing the note, it's going to modulate the position of PickupA. So if I play softly-- (music playing) --the pickup will be in one position. If I play with more velocity, then the pickup is moved elsewhere on the string. And if I play at different velocities, you can hear the pickup moving around. So notice there is a couple of different Velocity curves that we can have here. For example, we have this curve on the right here. What that's going to do is at lower velocities I am going to get more PickupA position modulation than, say, this curve on the other side.
So right now I have it set at the one in the center, which is Linear. So I will leave it there. So we have a second target as well. So I could set that, for example, to Pitch. So it's set to Pitch right now. And I have turned off the Target 1 modulation, just so we can hear pitch on its own. So I will increase the amount here and then depending on the velocity I play, I get a different pitch. Now if I set a negative velocity, that means when I play a harder velocity, (music playing) then I get a lower note.
So that's the way you can use a negative amount of modulation, in terms of the velocity here. So over on the right, we have these Note On Random parameters. What this has to do with is just hitting the note. So that sends a MIDI signal, that's a note on MIDI signal, but just doing that alone will create a random change in whatever our target is. So for example, I'll hit this Target 1 here, and I will send that to Pitch. So right now, I have no Amount for it, so I should play notes, and we don't have any pitch modulation, right? So now if I give this Amount, so I will move this to the right here, and I will play, for example, a C note-- (music playing) Notice that every time I play the C note, I am getting a different pitch.
(music playing) So the Note On signal is what's modulating the pitch. So I will set this back to the center here, and I have a second target right here. So I will turn that on. We will turn off Target 1, and let's set this to something different. So you can set this to String Stiffness. So I am going to get random changes in the stiffness of the string when I play notes. So I will give this an Amount here and now when I play a note, each time I play, I get a different amount of stiffness for my string material.
So we will go ahead and turn this off, and I'll take a look at this last tab here. So we have Controller A and Controller B. So what this allows us to do is use a MIDI Controller to continuously modulate some type of parameter in the sound engine. So let's start with Controller A. I will turn on Target 1 and then I choose a destination. So I am going to use PickupA Position. So then what I need to do is assign Controller A. So down in the MIDI Controller Assignment area, I will look over and I see Controller A. Right now it's set to the Mod Wheel and I can select this list here, and you can see I can assign it to any MIDI Controller or I can have it learn to a knob or fader on my MIDI Controller.
I am going to stick with ModWhl for right now. So what I have to do is give this a bit of amount here and so now when I use my Mod Wheel, I am moving the position of PickupA. (music playing) So I have this in Continue mode right now, so that means that at any point when I'm playing the note, I can adjust the Pickup position. If I click on this, that changes it to Note On mode, and what that means is I can only modulate it during the Note On portion of the sound. So I have a second target as well for Controller A. So I can assign it to something different.
So first, I am going to set this Pickup Position back to Continue, and then for Target 2, let's set that one to Pitch. What I will do is I will give it a negative amount, so that when I open up the Mod Wheel that the pitch will descend and then I will be moving the Pickup position to the right. So you can hear when I move the Mod Wheel that I am adjusting the pitch and I am moving the Pickup position as well. (music playing) So we will go ahead and turn this off. So if you take a look, Controller B functions exactly the same as Controller A.
So as you can see, there is a lot of different ways we can add movement and modulation with the Modulation parameters on the left side of the interface. In the next video, let's explore how we can add more movement, modulation, and expression using the control envelopes.
